WINDOW-SCREEN.

Specification of Letters Patent. P t te July 1 191 Application filed August 16, 1909. Serial No. 513,019.

To all whom it may concern,

Be it known that we, ARTHUR L. LADWIG and JOSEPH BUTKUS, citizens of the United States, and residing at Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in' VVindow-Screens, of which the following is a complete specification.

The main objects of this invention are to provide a window screen adapted to be automatically operated by the opening or closing movement of the window sash; to provide a window screen in which the screen members, are adapted, when the window is closed, to be contained Within a protecting box or casing, and when the window is open to be withdrawn fronrthe casing by the movement of the sash and to completely cover the window opening; to provlde an automatically operating window screen adapted to be adjusted to fit varying widths of windows; and to provide a device in which the screen members are so mounted that they may be easily removed from their casings and replaced when desired without the use of skilled labor.

A specific construction embodying said invention is illustrated in the accompanying drawings, in which:

Fig. 19 is a similar section, partly broken, and showing the clampin plate locked in closed position.

Fig. 20 1s a fragmentary, side elevation of a window with the casing in place, and showing means for securing the casing in the window opening.

In the construction shown a telescoping casing 1 is provided and is adapted to seat in the Window opening beneath the sash 2, and to abut at its ends closely against the Window frame 3. The casing is preferably provided with a bottom having the same incline as the Window sill 4:, and with a top having the same incline as the bottom of the sash 2, so as to form tight joints When the window is closed. Said casing comprises two telescoping sections 5 and 6, which are open along their upper, inner corners as at 7, and the margins of the outer section 5, along said opening, are rolled over to provide a sleeve 8 on one margin and a bead 9 on the other margin, and those on the inner section are rolled to'provide a bead 10 adapted to fit in the sleeve 8, and a sleeve 11 adapted to receive the head 9, as shown more clearly in Figs. 2, 3 and. 4.

The outer ends of the sections 5 and 6 are provided respectively with removable heads 12 and 13, which may be secured in place in any preferred manner, but, as shown in Figs. 3, 4 and 7, a portion of the end edges of the sidewalls of the sections are turned inwardly to provide flanges 14,

against which the heads seat. The heads are provided with outwardly turned flanges 15,

which are turned back upon themselves to provide hooks 16 adapted to engage over the margins of the casing. In this manner the heads are countersunk within the ends of the casing, as shown more clearly in Figs. 5 and 7. A locking bar 17 is pivoted on the inner side of each head by means of a pivot pin 18, and the outer end of said pin is provided with a handle 19 by means of which the bar may be operated. The ends of said bar are turned inwardly a short distance from the head and are adapted to engage behind the flanges 14 when the bar is turned transversely of the head, as shown in Figs;

6 and 7 v The head His rovided near its top with a bearing 20, an the section 5 is provided at its inner end with a bearing bracket 21, having a bearing therein in axial alinement with the bearing 20. In order to support the bracket 21 so that the inner section 6 may pass it, it is suspended from a plate 22 which is formed on the margin of the sleeve 8 and extends across the section and rests on a supporting head or ledge 23 on the inner side of the section 6, as shown in Fig. 2. The head 13 is also provided with a bearing 20, and at the inner end of the section 6 is a bearing bracket 24 having a bearing therein in axial alinement with the bearing in the head 13.

Mounted in the bearings of each section is a screen roller. Said rollersare parallel with each other, and are disposed one in the upper portion of the casing and, the other 1n the lower portion of the casing, so that as said sections are extended or re tracted the rollers move longitudinally with respect to each other.

Each roller comprises a barrel or shell 26, of wood or other suitable material and is provided on each end with aninner ferrule or cap 27, which is rigidly secured thereon and is provided with a bearing sleeve 28 extending axially-into the barrel and out of contact therewith. An outer ferrule orcap 29 is rotativel secured on the inner ferrule and is provi ed in its outer end with an aperture in axial .alinement with the sleeve.

28 but of larger diameter. A flange 30 extends inwardly about the aperture and abuts against the end of the ferrule 27. A tubular rivet 31 extends through the sleeve 28 and has its inner end swaged over the inner end of the sleeve. The head 32 of said rivet overlaps the outer end of the ferrule 29, and is provided with a shoulder 33 which rests against the end of the ferrule 27.

Extending axially and projecting from the ends of the barrel 26 is a rod 84,'which at the end adjacent the outer end of the casing section is provided with a collar 35 which has a bearing'in the rivet 31. On the outer end of the collar 35 are ratchet teeth 36, and a spring pressed pawl 37 is pivoted'on the outer side of the head and engages said ratchet teeth. A helical spring 38'is contained in the barrel around the rod and has its 'end adjacent the ratchet en-.

wire netting or other screen member 43 X which sheets unroll from the same side of the rollers, or that side adjacent the opening 7 in the casing, and overlap and lie in close contact with each other. For the purpose of detachably securing the screen members to the rollers, each barrel is provided in 'its outer surface with a longitudinal groove 44, which is eccentric to the periphery of the barrel, and a transversely curved attaching plate 45 is hinged therein. Said plate is provided in each end with a notch 46, which provides hinge arms 47 at the rear of the plate. Said arms lie in the groove beneath the ferrule 27 as shown more clearly in Figs. 12, l3, l8 and 19, and the ends 48 of the plate, on the opposite side of the notches from said arms, are adapted to lie on the outer side of the ferrule 27, as shown in 19. The outer ferrules'29 are each provi ed with a notch 49, the rear margin 50 of which is slightly raised to permit it to pass over the end 48 when rotated in one direction, and when rotated in the opposite direction the ferrule will pass beneath the end 48, and the forward edge of the plate may then be swung away from the barrel to permit the edge of the screen member to be inserted. beneath it. The forward edge of the plate is provided with teeth 51 which engage the member when the plate is again closed or turned against the barrel. When the ferrules 29 are rotated to bring them over the ends 48, the screen member is held securely in place.

The outer edge of one screen member 43 is provided with a. binding strip 52, which is folded to clamp the margin of the screen member therein, and the other member 43 is provided with a binding strip 53 which has a channel 54 formed on the top thereof to receive the strip 52, as shown in Figs. 9 and 10.

For the purpose of attaching the upper margins of the screen members 43 to the sash, clips 55 are provided, which have books 56 at their lower ends adapted to be hooked into the folds of the binding strips and permit adjustment longitudinally of the strips. At their upper ends said hooks are provided with teeth 57 which are adapted to engage the lower sash rail.

Any preferred means may be provided for securing the casing in the window opening, but, as shown more-clearly in Fig. 20, longitudinally slotted bars 58 and 59 are each pivoted at one end to the side of the overlap at their free ends.

'ject the ends of the plate casing, near one end thereof, and said bars The bars are each provided with teeth 60 on their upper edges, and a link 61 is carried in the slots 62 in said bars and is adapted to be inserted between the teeth of said bars when the bars are at an angle to each other, as shown in dotted lines. When the bars are forced to parallel relation the link prevents them from moving longitudinally of each other and causes them to move the casing sections into binding contact with the window frame.

The operation of the construction shown is as follows: The screen rollers are placed in their respective casing sections with the screen members wound thereon and having their upper margins projecting through the opening 7. When the sections are put together the rollers lie one above the other and may pass each other when the sections are adjusted to vary the length of the casing. By taking hold of the projecting margins of the screen members the barrels 26 may be held from rotation while the rods 34 are rotated in a direction to partially wind up the springs 38. When the springs have been wound sufiiciently to apply the desired tension to the screen members they are held from reverse movement by the ratchet teeth and pawl 36 and 37. The upper margins of the screen members are connected by the telescoping binding strips which may be adjusted to the Width of the window opening. By means of the adjustable clips 55 the screen members may be secured to the sash. When the sash .is raised the roller springs are further wound up by the unrolling action of the screen members. When the sash is lowered the-springs cause the barrels to rotate and roll the screen members thereon, thereby retracting them into the casing. When itis desired to replace the screen members bynew ones, the casing heads 12 and 13 may be unlocked and removed and the rollers withdrawn. The binding plates 45 are then released by rotat ing the ferrules 29 in the direction to profrom the notches 46. When it is not desired to use the screens the casing is removed from the window opening and the sections are forced together, so as to occupy a minimum amount of space. The casing may then be stored away with the screen members entirely protected by the casing.
